In vitro susceptibility of penicillin-resistant Streptococcus pneumoniae to levofloxacin, selection of resistant mutants, and time-kill synergy studies of levofloxacin combined with vancomycin, teicoplanin, fusidic acid, and rifampin.

Abstract excerpt

Among 180 clinical isolates of pneumococci, no strains were found to be resistant to levofloxacin (MIC, > or = 4 micrograms/ml) whereas 9% were resistant to ofloxacin and 7% were resistant to ciprofloxacin. Synergism was demonstrated by time-kill studies in nine of nine strains for the combination of levofloxacin and vancomycin and in six of nine strains for levofloxacin plus teicoplanin. The combinations of...
